Genesis 6:4

2 the sons of God saw that the daughters of humankind were beautiful. Thus they took wives for themselves from any they chose. 3 So the Lord said, “My Spirit will not remain in humankind indefinitely, since they are mortal. They will remain for 120 more years.” 4 The Nephilim were on the earth in those days (and also after this) when the sons of God would sleep with the daughters of humankind, who gave birth to their children. They were the mighty heroes of old, the famous men. 5 But the Lord saw that the wickedness of humankind had become great on the earth. Every inclination of the thoughts of their minds was only evil all the time. 6 The Lord regretted that he had made humankind on the earth, and he was highly offended.

(It is noteworthy that his sarcophagus was made of iron. Does it not, indeed, still remain in Rabbath of the Ammonites? It is 13½ feet long and 6 feet wide according to standard measure.) 12 This is the land we brought under our control at that time: The territory extending from Aroer by the Wadi Arnon and half the Gilead hill country with its cities I gave to the Reubenites and Gadites. 13 The rest of Gilead and all of Bashan, the kingdom of Og, I gave to half the tribe of Manasseh. (All the region of Argob, that is, all Bashan, is called the land of Rephaim.
